Simplifying Your Python Command-Line Interface with Click
Streamlining your Python command-line interface development with Click
Creating a Command-Line Interface (CLI) in Python can be time-consuming, but the Click library makes it easy. Click provides a simple and intuitive interface for defining commands and options, as well as handling input and output. It also includes useful features such as command chaining, automatic help generation, input validation, and error handling.
To get started with Click, simply install the library by running the command:
pip install click
Here's an example of a simple command that takes two numbers as arguments and prints their sum:
import click
@click.command()
@click.argument('first_number')
@click.argument('second_number')
def add(first_number, second_number):
result = int(first_number) + int(second_number)
click.echo(result)
if __name__ == '__main__':
add()
If you're looking to create a CLI for your Python program, you can read more about click in Creating a Command Line Interface and also click official documentation.
